My son is 8 years old, and we found out that he is allergic to citrus fruits. There's no one in my family with this allergy. What could have caused it in him?
There are a lot of adverse reactions to citrus fruits though most of them are not truly allergic in nature. I would advise that you see an allergist who will be able to not only test him but give you suggestions based on the history and type of his reaction.
